Investigators believe his parents tried to call for help during the gruesome attack; a telephone in their home was off the hook and covered in blood. Their son, who went to Stuyvesant High School and Williams College but had a history of mental problems, allegedly cleaned himself up and fled to Newark Airport, catching a plane to Tel Aviv before his parents bodies were discovered Wednesday night.

The international manhunt ended at Tel Aviv's Ben Gurin airport when Bellucci had trouble buying a Turkish Airways ticket to Beijing Friday. His credit card was rejected and when the ticket agent told him to return with cash, she recognized his face from media reports and called authorities.

"The passenger looked unstable, he was talking to himself, he looked nervous," said Liron Cohen, the ticket agent.

Family friend Frank Floridia said Eric Bellucci had stopped taking his medication and wasn't getting along with his mother.

"Artie would tell me that Eric was always arguing with his mom," said Floridia. "It was Eric and his delusions as to what was going on with his mom."

Police responded to a 911 call to the Bellucci home on Poillon Avenue just after 8:30 p.m. Wednesday and found the couple stabbed numerous times. Their daughter, who recently moved out because of her brother's behavior, called police after checking on her parents and finding blood in the foyer.

Police reportedly had been called to the Belluccis home on multiple occasions because of Eric's volatile behavior.

"They sacrified everything for their kids and made the ultimate sacrifice in this situation," said next door neighbor Ben Pistilli.
